Abstract: An image sensing apparatus has a light sensitive area and a control unit. The light sensitive area registers image data in response to an incoming amount of light, and is operable in an active mode wherein image data can be read out there from as well as in a standby mode wherein image data cannot be read out. The control unit produces a control signal setting the light sensitive area to operate in the active mode and the standby mode respectively in a cyclic manner during an operation period, which preferably encompasses multiple data frame read-outs of image data from the light sensitive area.
Abstract translation: 图像感测装置具有光敏区域和控制单元。 感光区域响应于入射量的光来记录图像数据，并且可以以活动模式操作，其中可以从其中读取图像数据以及不能读出图像数据的待机模式读取图像数据。 控制单元产生一个控制信号，在操作期间分别以循环方式设置光敏区域以工作在活动模式和待机模式，优选地包括来自光敏区域的多个数据帧读出图像数据。

Abstract: Circuitry of a gaze/eye tracking system obtains one or more images of a left eye and one or more images a right eye, determines a gaze direction of the left eye based on at least one obtained image of the left eye, determines a gaze direction of the right eye based on at least one obtained image of the right eye, determines a first confidence value based on the one or more obtained images of the left eye, determines a second confidence value based on the one or more obtained images of the right eye, and determines a final gaze direction based at least in part on the first confidence value and the second confidence value. The first and second confidence values represent indications of the reliability of the determined gaze directions of the left eye and the right eye, respectively. Corresponding methods and computer-readable media are also provided.

Abstract: At least one image registering unit records at least one series of images representing a subject. A control unit controls an operation sequence for the at least one image registering unit in such a manner that a subsequent data processing unit receives a repeating sequence of image frames there from, wherein each period contains at least one image frame of a first resolution and at least one image frame of a second resolution being different from the first resolution. Based on the registered image frames, the data processing unit produces eye/gaze tracking data with respect to the subject.

Abstract: A visual display includes hidden reference illuminators adapted to emit invisible light for generating corneo-scleral reflections on an eye watching a screen surface of the display. The tracking of such reflections and the pupil center provides input to gaze tracking. A method for equipping and an LCD with a reference illuminator are also provided. Also provides are a system and method for determining a gaze point of an eye watching a visual display that includes reference illuminators. The determination of the gaze point may be based on an ellipsoidal cornea model.
